About the Role

We're hiring a Backend Engineer for a full-time, on-site role in Pune. You'll take ownership of core server-side systems, driving key architectural decisions and setting technical standards across the backend. Beyond building and optimizing high-performance APIs, you'll be a technical anchor for the team — mentoring engineers, reviewing designs, and making the tradeoffs that keep our platform scalable as it grows. You'll partner closely with front-end and AI/ML engineers to ship features end to end, and you'll be a go-to voice when the team hits gnarly performance or integration challenges.

This is NOT a entry-level position — we are not considering interns, new graduates, or entry-level

candidates for this role.

What You'll Do

• Own the design and architecture of backend systems, from high-level structure to low-level implementation
• Set technical direction and best practices for backend development across the team
• Build and optimize APIs for performance, reliability, and scale
• Mentor and provide technical guidance to other engineers, including code and design reviews
• Diagnose and resolve complex performance bottlenecks and system-level issues
• Collaborate cross-functionally with front-end, AI/ML, product, and UX teams to deliver cohesive features
• Make build-vs-buy and architectural tradeoff decisions with long-term scalability in mind

What We're Looking For

• 4+ years of backend development experience, with deep expertise in Python, Node.js, and Express.js
• Strong hands‑on experience with MongoDB and PostgreSQL at scale; Azure deployment experience strongly preferred
• Proven track record owning system architecture and leading technical decisions in production environments
• Deep understanding of object-oriented design and software design patterns
• Working knowledge of front-end development to collaborate effectively across disciplines
• Experience mentoring engineers or leading technical initiatives
• Comfort operating with high autonomy in a fast-paced, mission-driven startup
• Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience)
